Abstract
aspectos da revelação incluem um método de codificação de vídeo. o método inclui receber dados de entrada associados a um primeiro bloco e um segundo bloco de um quadro de imagem, sendo que o primeiro bloco e o segundo bloco correspondem a componentes de espaço de cor diferentes. o método inclui, ainda, identificar uma região de referência no primeiro bloco, identificar pelo menos duas células de unidade de referência dentre uma pluralidade de células de unidade na região de referência, identificar os respectivos modos de intrapredição para processar as células de unidade de referência identificadas, determinar um modo de intrapredição para processar um sub-bloco no segundo bloco com base nos modos de intrapredição identificados e gerar um intrapreditor do sub-bloco com base no modo de intrapredição determinado. a região de referência e o sub-bloco correspondem a uma mesma região no quadro de imagem. o método inclui, ainda, codificar ou decodificar o sub-bloco com base no intrapreditor do sub-bloco.
